Ok we need to add and/or alter these two terms:
Re
Marche and Marcheur:
. .
Marche (f) - Cocking and extracting/ejecting mechanism?
. . . . .Comment: La marche d'un fusil est composée de pièces qui se mettent en mouvement quand tu ouvres le fusil. ("La marche" of a gun is composed of pieces which move when you open the gun.)
. .
Marcheur (m) - Barrel cocking and extraction/ejection fabricator?
Re
Bascule and Basculeur:
I had Bascule:
. .
Bascule (f) - receiver/action
. . . . .
Bascule ronde - round receiver
And Basuleur:
. .
Basculeur (m) - Action filer; Action maker
However Basculeur per Fab and Larry is:
. .
Basculeur (m) - Joiner or barrel joiner. (Le basculeur est la personne qui monte les canons sur la bascule.)
Could we come to a consensus on this before I add it to the dictionary? (Fab is the expert - I'm just looking for a good English word to use):
